My denon ADV-500SD is giving 'protect' cut out everytime around certain volume. Any thoughts how to fix?
cheers Bob
Hi bob
I`m going to help you with your receiver but first i`d have a few question;
Is this a new setup or did you change anything in your setup lately?
Does it do the same with only the headphones on?
Hi again Bob
It may be then that one of your speaker may have developed a problem although sometimes it is hardly noticeable just by hear.
Of course the pro way of doing this would be to measure the impedance of each line with an impedance meter.
An ohmmeter or multimeter set in ohm would be the second best choice to measure the lines and find if they are within specs, that is between 4 and 16 ohms usually(6 ohms in your case).
Another way of doing this would be to disconnect the speakers one at a time and try it between each speakers.
Then if the problem still persist there could be the fact that the receiver has developed a fault either in the output stage/protection circuit or power supply.
Try it and let me know
be waiting for your reply
glad to be of help thank you

Hi Guru, thanks for help.
This set up is a few years old - multimedia in a church hall - and has been working no problems. No recent changes, the last addition was monhs ago and everything has ben fine 'til this week. Have just tried headphones and yes they are ok right up to max volume whereas every other medium cuts out at between 63 and 67 on the volume.
cheers
Bob
Ok, will try disconnecting speakers first and let you know. Thanks
Disconnecting one speaker has sorted the problem. I presume testing a replacement will confirm that the speaker has a fault.
Thanks for your help
yes, sorted, many thanks. Bob
